@pzmyers Musk is turning into a Bond villain. I half expect a tuxedoed MI6 agent to be taking him out sometime in the next few years...

M82 is a galaxy in Ursa Major. It is interacting with nearby galaxy M81 which is causing massive star formation within M82.

NGC 2903 is a barred spiral galaxy located about 30 Mly away in the constellation of Leo. A barred spiral galaxy has at its centre a "bar" of stars, an elongated part of the core where much star formation occurs. Bars seem to be temporary as they're unstable gravitationally.

NGC 3593 is a starburst galaxy located about 20 Mly away in the constellation Leo. A starburst galaxy is undergoing massive star formation, often due to interaction with nearby galaxies. NGC 3593 is classified as a lenticular galaxy, so intermediate between spiral and elliptical.

NGC 3628 is an edge on spiral galaxy located about 35 million ly away in the constellation Leo. Sometimes called the Hamburger Galaxy, along with M65 and M66 is also part of the Leo Triplet of Galaxies.

For comparison to last night's line filter image, here is M42 taken through regular RGB filters, showing what the human eye would see if M42 were bright enough to see colour.

Using different filters can show different things. This image of the Great Nebula in Orion was taken using filters that only see spectral lines of hydrogen, oxygen and sulfur. Those images were then mapped to a regular RGB image. The blue shows the O, the green H, and red S.

They're only Lewis diagrams if they come from the Lewis region of France, if not they're only sparkling electron dot diagrams...

M87 is an extremely massive elliptical galaxy located about 57 Mly away in the constellation of Virgo. The jet seen going to the right is caused by the supermassive black hole at the centre of the galaxy.

Age poll pt. 2! Again, this may not apply to you (refer to previous toot if it doesn't).

Hello all! In the interest of finding out how the Fedi skews, I want to run another age poll. Please pick the decade that you fall in (there are two polls; if you don't belong in the first, you may belong in the second).

Boosts welcome and encouraged!
